Function & Application
Medical X-ray image intensifier is the Electronic Equipment which changes the input of x-ray image into the output of visible image. It is installed on the x-ray TV system, which is applicable to the x-ray fluoroscopy and radiography.
Construction & Sort
X-ray image intensifier is composed of x-ray image multiplier tube, tube container, high voltage power supply which is set inside of tube container and the low voltage power supply which drives the high voltage power supply.
Application & Performance
It is applicable to the medical x-ray image intensifier which nominal entrance field of view is 23cm (9in). Especially it can replace Toshiba E5830 x ray image intensifier. With same installation holes.

Fault & Maintenance
Fault Phenomena | Possible Reason | Resolvent |
No Image | Without 24V low voltage DC power supply. | Check 24V DC power supply box, and ensure the normal power supply. |
Whether the 24V low voltage DC power supply is normal, the cable is broken off or contact bad. | Connect cable normally, and if it broken off, please mend. | |
X-ray machine doesn’t produce rays. | Maintain x-ray machine or check the collimator whether is in the turnoff state. | |
The high voltage box is damaged. | Replace the HV Power Supply box. | |
Definition Reduction | HV box focusing voltage excursion. | Adjust Gadj potential device to proper position again. |
Low voltage power supply excursion. | 24V DC power supply voltage excursion, and adjust it to 24V again. | |
X-ray tube aging. | Replace x-ray tube. | |
Output screen is dusty. | Dedust and clean. | |
Image distortion or fluctuation. | It has strong magnetic field around. | Find and remove strong magnetic disturbance. |
Microwave radio frequency disturbance. | Remove the disturbance source or turn off the radio frequency radiant device. |
